The AMD Fast CPPC feature enablement for the "amd_pstate" driver has been submitted to the power management subsystem ahead of next month's Linux 6.11 merge window.

OpenSUSE Leap 15.6 is now officially available for this community Linux distribution release aligned with SUSE Linux Enterprise 15 Service Pack 6. With Leap 15.6 comes the inclusion of the Cockpit web administration software and many software updates.

Intel Low Power Mode Daemon v0.0.4 has been released with "LPMD" being the open-source daemon for optimize active idle power for modern Core hybrid CPUs under Linux that sport a combination of the E and P cores.

Merged today to LLVM Clang 19 Git is support for the #embed resource inclusion mechanism that is an approved C23 feature. This also makes Clang the first for supporting this pre-processor embed feature.

Well known open-source AMD OpenGL/Gallium3D driver developer Marek Olšák has landed a big patch series into Mesa 24.2 for a universal optimized compute image clear/blit shader and MSAA-resolving pixel shader.

Intel's oneDNN 3.5 has been released as this Deep Neural Network Library for the oneAPI specification and now part of the UXL Foundation. With oneDNN 3.5 comes more performance optimizations for existing and upcoming Intel hardware.

The extensible scheduler "sched_ext" code has proven quite versatile for opening up better Linux gaming performance, more quickly prototyping new scheduler changes, Ubuntu/Canonical has been evaluating it for pursuing a more micro-kernel like design, and many other interesting approaches with it. Yet it's remained out of tree but that is now changing with the upcoming Linux 6.11 cycle.

Systemd 256 is out today as the latest major feature update to this integral component to modern Linux distributions.

The Raspberry Pi 5 features the "RP1" as the in-house silicon design for the southbridge to this single board computer. The RP1 driver maintained by Raspberry Pi is just found in their downstream kernel while a SUSE engineer is working to rework that driver so that it can be eventually mainlined in the upstream Linux kernel.

Merged last month to the GNU C Library (glibc) Git code was a new tunable for non-temporal stores for memset. This optimization for glibc's memset performance was limited to Intel processors given at the time it was only tested/benchmarked on Intel CPUs but now it's proven to be useful too for AMD processors.

Coincidentally coming out on the day of Raspberry Pi's IPO is AlmaLinux providing official support for the Raspberry Pi 5.

While last year we saw Fedora to no longer omit the frame pointer to help in debugging/profiling Fedora packages and Ubuntu 24.04 LTS also enabled frame pointers for better debugging/profiling, among other distributions, there is the known performance implications of no longer omitting the frame pointer. But now in aiming to make the best of both worlds, it turns out Red Hat has been developing eu-stracktrace as a new means of profiling without relying on frame pointers.

Last month AMD Linux engineers posted ap atch series for better handling heterogeneous core type CPUs. This is for enhancing the P-State CPU frequency scaling on CPUs featuring a mix of conventional cores and efficiency cores, e.g. Zen 4 and Zen 4C. A third iteration of these patches were posted today.

Google is known for their many contributions to open-source compilers and particular many different sanitizer efforts over the years. Their newest project they have made open-source in this area is GWPSan as a sampling-based sanitizer framework.

Raspberry Pi carried out a successful IPO today on the London Stock Exchange.

Last year it was announced that Intel's oneAPI software initiative evolved into the UXL Foundation for making compute accelerators more open as well as opening things up to more cross-vendor collaboration and adoption. Intel started the Unified Acceleration Foundation with the Linux Foundation, Google, Arm, Qualcomm, Samsung, and others. Announced today is that the UXL Foundation has begun collaborating with The Khronos Group.

Covered last week on Phoronix was a new patch from Intel that with tuning to the P-State CPU frequency scaling driver was showing big wins for Intel Core Ultra "Meteor Lake" performance and power efficiency. I was curious with the Intel claims posted for a couple benchmarks and thus over the weekend set out to run many Intel Meteor Lake benchmarks on this one-line kernel patch... The results are great for boosting the Linux performance of Intel Core ultra laptops with as much as 72% better performance.

Bavarian Linux PC vendor TUXEDO Computers is working on bringing a Snapdragon X Elite powered laptop to market.

Mozilla Firefox 127.0 binaries are available for download today ahead of tomorrow's official announcement. Firefox 127 brings a few nice changes for this month's feature update.

After an attempt in early 2023 didn't pan out, today an AMD Linux engineer posted a new kernel patch series for enabling per-core RAPL energy counter support for AMD processors. With this patch series when using Linux's venerable perf utility it's now possible for reading the power use on a per CPU core basis using a new "power_per_core" PMU.
